"Smash" Block Manipulation

I've always pondered how the minigame "Smash" has achieved the ability to manipulate blocks in the way where you are able to change the x, y, and z of a block/entity without "grid-snapping".

Is there a "hack-erish" way to achieve this, or is this described in the Bukkit API to be achieved?

I thought editing the NBTTag of blocks would enable this, but sadly it seemed to have not.

 

Falling block entities.

 

It isn't that hard really, you have to create a falling block entity as Garris0n said.

Code:java

 @EventHandler
public void onPlayerMove(PlayerMoveEvent event)
{
Location loc = player.getLocation().add(0, -1.0, 0);
Block block = loc.getBlock();
 
FallingBlock fall = block.getWorld().spawnFallingBlock(block.getLocation(), block.getType(), block.getData());
Vector veloc = fall.getVelocity();
veloc.setY(veloc.getY() + 2);
fall.setVelocity(veloc);
block.setType(Material.AIR);
}
}

This is my class for the mechanic. What this does is if a player stands on a block, the block will fly up and then land back down, it's used for a Spleef type mini-game I created.

Hope this gives you a good idea of how to use it.
